New Pratt & Whitney Center of Excellence expands gas turbine research
The Ohio State University is accelerating its investigation of jet engines and gas turbines, thanks to a collaboration with aerospace manufacturer Pratt & Whitney. A multi-year agreement will establish the Pratt & Whitney Center of Excellence in the Gas Turbine Laboratory, located at Ohio State's Aerospace Research Center.
The center’s activities will begin with the development of an innovative high-temperature rig in which turbine engine blade tip rub experiments can be conducted. Turbine blades operate within a structured casing in the engine—required minimal clearance between the two poses a risk for the blade’s tip rubbing on the casing, resulting in potential performance degradation or even system failure.
“Ohio State’s Gas Turbine Lab has a great deal of expertise in blade tip rub research,” said Kiran D’Souza, assistant professor and principal investigator of the center. “We’re proud to partner with Pratt & Whitney to investigate solutions to this industry-wide issue.”
Assistant Professor Randy Mathison, co-principal investigator, further described the center’s research initiatives. “The goal of the center is to develop a better understanding of blade tip rub dynamics and material characterization at design-speed and engine-relevant temperatures.”
Professor Emeritus Mike Dunn, also a co-principal investigator with the center, brings over 50 years of gas turbine expertise to the research initiatives.
The new center joins the department’s Pratt & Whitney Center of Excellence in Gearbox Technology, housed in the Gear and Power Transmission Research Laboratory.
